Lecture: Understanding Eyepieces, Enhancing the View at Custer Observatory

You have your telescope and you have been having fun finding and observing the wonders of the sky. But you would like to expand your tools. The next thing you will want to add are eyepieces and perhaps a barlow lens. The ones that came with your scope are only a starting place. Ed will discuss how eyepieces work, what the specifications mean and how you would choose the right ones for your telescope to achieve your goals within your budget. Ed will bring examples. After the presentation, if conditions are favorable, Custer will have telescopes to provide wonderful views of the sky. Ed will open the ASLI dome, behind Custer, which houses a 14″ Meade LX200 computerized telescope for those who would like to take a look at the sky through this scope and see how a change in eyepiece might enhance your enjoyment of the things you are observing.
Stargazing (weather permitting) will follow.
